The Pioneer 70 incorporates Britaxs leading safety innovations, including their patented Head-Safety technologies such as: Base with SafeCell Technology, Integrated Steel Bars, and Energy Absorbing Versa-Tether. These components work together to protect your childs head by minimizing forward movement during a frontal impact

True Side Impact Protection provides deep side walls and a head restraint with energy-absorbing EPP foam to distribute crash forces, shield from vehicle intrusion, and contain the head, neck and body while keeping them “in true” or aligned

Base with SafeCell Technology designed to keep your child safe and secure in a crash by compressing and significantly lowering the center of gravity, reducing the forward movement of the car seat

Integrated Steel Bars strengthen the connection to the vehicle and reduce forward flexing of the child seat during a crash

Energy Absorbing Versa-Tether anchors the top of the car seat to the vehicle using a two-point attachment, minimizing the amount of forward movement of the car seat. Stage-released stitching helps reduce the crash forces reaching the child

Compatible with SecureGuard which works with the vehicle safety belt in booster mode to prevent the child from sliding under the lap-belt portion of the safety belt during impact, thus minimizing the risk of abdominal injury (accessory sold separately)

Comfort Foam provides an extra layer of padding to cushion your child

Quick-Adjust No-Rethread Harness easily adjusts the harness shoulder height and head restraint from the front of the seat without disassembling the harness straps
